Should I Rent or Sell?

[Chris A.]

I have my first home that I purchased as a foreclosure back in 2011 which up until now has been our primary residence.  I got a great deal on it and planned on it being my first rental property when we decided to find another primary.  

So fast forward to today, my and my wife have had 3 kids and decided its time to move on from the house.  We moved in with my parents while we decide what the next step is as far as where we plan to move to.  The question now is if we should continue with the original plan of renting it out or just sell it and use the cash to fund some flips and pay off some medical bills.

Here's the financial situation:

Currently owe 91k on the house, comps in my neighborhood suggest I could get 175-185 realistically.  I have a heloc, which I would take a 400$ hit on early termination if I sold.  I could rent the house out for 1400.  Current mortgage payment is 790. 

I have around 22k in credit card debt from medical debt from my wife and some from fixing things in the house to get ready to sell/rent. 

Obviously, I've got a lot of equity I can pull out in a refi, which I could use to pay off most of my credit card debt and cash for a flip if I found a good deal.  Would it be more advantageous to sell and get the large lump sum to make cash offers, or cash flow, take out some money out in a refi to pay off some of the cc debt and stash some for a good flip deal.  If I were to do a refi, what's a good amount to start out with for doing flips? 

Thanks for any input!
